Base image
----------

ska-tango-images-tango-python contains all the system dependencies required to run
a built with ska-python-build.  PyTango-based applications
built with this build image can be copied into a image based on
ska-tango-images-tango-python to produce a lean runtime image for the application.
See :ref:`build-pytango-image` for details about how to build your own Tango
application images.

Runtime application images using ska-tango-images-tango-base as a base image
will run as a "tango" user by default.  This user has sudo privileges.

In addition, the runtime application image will contain orchestration scripts to
aid with starting Tango device servers.  See :ref:`ska-tango-images-tango-base`
for usage of these orchestration scripts.
